Wow! Do you know how hard it is to deposit a flat metal plate without using a substrate? Our gearheads are sorting out how it can be done as we perfect the +1000K’s Arc Metal Deposition technology. See the below photo of a 1 kg steel part deposited in about an hour. Sorry, but we would make you drool if we told you how little it cost us to make this part.
Our goal is to make a metal part using less than half the energy required for sand casting while letting you use less material to achieve the same strength. Lofty goal, yes – but the +1000K just might be the machine to do it! Check out this picture of a tensile test sample made in about 5 minutes.
For the techies out there, this part took about 1.1Kwatts/kg of electrical energy, and is close to full tensile strength as it has no porosity. (For comparison casting requires 1.6KW/Kg of energy to make a part – see the Paper Attached from the July 2014 International Journal of Precision Engineering and Manufacturing-Green Technology)… so we are almost there!
